This PR fixes an issue introduced in #20372 that was causing slash
commands provided by context servers to not show up in the completions
menu.
Release Notes:
- N/A
This PR reworks how the Assistant Panel references slash commands,
context servers, and tools.
Previously we were always reading them from the global registries, but
now we store individual collections on each Assistant Panel instance so
that there can be different ones registered for each project.
